About X chromosome testing
Females have an XX chromosome pair in every cell. One of the chromosomes in each pair is inherited from the mother and the other inherited from the father.
- The X test is classified as a sibling test and its most common use is between females who wish to confirm whether they have the same father. For an X chromosome test to be accurate, the females involved need to have different mothers. In this case, the test will confirm whether they are half sisters or unrelated.
- In cases where two females share the same mother and want to establish if they share a biological father, an X-chromosome test can be carried out but only if the mothers sample is available for testing. Only with the mother’s sample can we determine accurately whether their X chromosome patterns match, confirming that they share the same identical X chromosome profile inherited from their common biological father.
- The X chromosome test can be used between paternal grandmother and granddaughter as they must share one X chromosome. This shared X chromosome is the one that the grandmother passed to her son and he, in turn, passed to his daughter. We only need DNA samples of the paternal grandmother and granddaughter for this test. We require no other samples in this particular case.
